About Grinding Cup Wheel
Grinding Cup Wheel Specification
There are certain specifications need to follow in case of grinding cup wheel such as :
- Never initiating grinding in the outside of a cup wheel
- If a cup type grinding wheel looks bumped or damaged then it should be discarded.
- Working with the grinding wheels
Grinding Cup Wheel Applications
Cup type Grinding wheel is used in tool and cutter grinders were having an additional radial grinding surface is beneficial. In cup grinding, a very shallow cup type grinding is done in slots and crevices is used in generally cutter grinding and also jig grinding. Critical parameters required are the fast cut-rate, smooth vibration-free running and the better life.
There are many styles and terms of diamond grinding cup wheels to fit different application specifications. The ones with several big diamond segments can move heavy workloads, for example, grinding cement and stone, while those with tiny or rare diamond segments are commonly utilized for fast replacement of paints, wallpapers, adhesives, epoxy, and other facade covers.
Just like other metal-bonded diamond means, the diamond sections on diamond grinding cup rings can have many bonds, several diamond grits, another diamond quality, and various diamond bands to fit various uses. For example, if the substance to be ground is hard, the bond should be more flexible, and if the matter is almost soft, the bond should be harder.
Cup Grinding Wheel’s Structure
Cup Grinding Wheels are named Cup Wheels, as the appearance is like a cup and there are two kinds of the same. One is straight and the other is tapper kind Cup Wheels. These cups have a rear wall and round sidewall. Cup type grinding wheel’s walls mainly the sidewall is utilized to crush the job. Although, both the surfaces are of particular thickness but it can be performed on special demands and terms of the customers.
Thicker walls are usually for more element removal, while thinner walls are applied for precise grinding. Industries like automotive sheet spring construction, blades production use the cup wheels, apart from many other construction sectors which need extra radial grinding surface.
Grinding cup wheels work with their features in common for surface grinding & sharpening of devices like a paper cutter, circular tools, etc. One more cutting without a round shape comes by the name of the segment.
Manufacturing Methods of the Cup Grinding Wheel
The grinding cup wheel manufacturing follows two steps:
- Hot Pressing
- Cold Pressing
In the hot pressing process, the diamond segments sinter in molds. Then under certain pressure into the press machine. These are fixed into the diamond segments onto the grinding wheels using
- high-frequency welding,
- laser welding
- and mechanical mosaic method
Cold Pressing Method
In the cold pressing method, you first have to press the working layer. Next, go ahead to press the transitive layer of the diamond segments onto the grinding wheel body. Then connect the segments with the help of the wheel’s body teeth. These segments are then sintered onto the furnaces so that they can be sintered without a press.
The cup-shaped grinding wheels (installed on the concrete grinders) are useful to grind the abrasive building materials such as
- Marble Etc.
Cup Grinding Wheel FAQ
Grinding cup wheel T6 (straight cup) & 11 (taper cup) are designed for use on vertical, right angled head, on vertical surface grinding machines.
Grinding is done on the rim of the wheel and work to be ground is held on platens or plain surface tables either magnetically or by means of fixtures that clamp the work to the table.
These tables or platens may be either rotated or reciprocated.
HA grinding cup wheels made from sharp brown, white ,pink aluminium oxide and silicon carbide grains suited for variety of materials. Better cut and finish and longer lasting than competitive products.
